摘 要:目的:研究银杏叶提取过程中总黄酮醇苷的快速检测方法。方法:近红外光谱技术与高效液相色谱法结合,采用偏最小二乘法建立银杏叶提取过程中槲皮素、山柰素、异鼠李素指标的定量校正模型。结果:槲皮素、山柰素、异鼠李素的定量校正模型相关系数(r)分别达到0.992 4、0.998 4和0.985 0,交叉验证均方差(RMSECV)分别为0.062 4、0.050 9和0.024 1,定量校正模型性能稳定,预测效果良好。结论:近红外光谱透射技术可以有效反映银杏叶提取过程总黄酮醇苷含量变化信息,可用于银杏叶提取浓缩过程的快速检测。Objective: To develop a rapid method for determination of the total flavone glycosides during the extraction process of ginkgo leaf. Method: Near-infrared spectroscopy combined with HPLC was applied to establish partial least squares models for determination of quercetin, kaempferide and isorhanmetin during the extraction process. Results: The correlation coefficients ( r ) of quantitative calibration models for quercetin, kaempferide and isorhamnetin were 0.992 4, 0.998 4 and 0.985 0, respectively. And the values of root mean square error of cross validation ( RMSECV ) were 0.062 4, 0.050 9 and 0.024 1, respectively. The models performed stable with good predictability. Conclusion: Near-infrared spectroscopy could reflect the variation of total flavone glycosides during the extraction process, and could be used in rapid analysis of the extraction and concentration process of ginkgo leaf.
